Good job Tavis, you are making the world safer, one enterprise deployment at a time.

In summary, Tavis Ormandy is a Jedi who apparently waves his hand at software and bugs fall out at his feet.
#Norton antivirus definitions mac Patch#
It should also be noted that the blog post includes links to even more details including example exploit code, so patch away. There are a number of other flaws, but really, this one is bad enough. This was the main vulnerability discussed in the security bulletin and in Tavis’ blog post. It is also possible that multiple affected products with different patching options may be deployed within a single organization, so again, check the advisory.
#Norton antivirus definitions mac update#
In some (but not all) cases, a normal update to the antivirus “defined definitions” will deliver the needed patch, but some organizations may want to force a manual update of the defined definitions as quickly as possible to ensure systems are immediately patched. It is highly recommended that you check this security advisory to ensure you follow the correct steps to patch any affected products you are using. Symantec has made patches available for the affected products in their security advisory. If the Symantec product runs on the email server, then the attacker just ran code of his choosing on your email server with administrative privileges. If the Symantec product is the desktop, just receiving the file in email is enough - it doesn’t have to be opened, the antivirus product does that for you to check it. This can be in email, IM, whatever - as long as Symantec’s thorough engine that checks files for maliciousness can touch it for examination, it can be triggered. Or send them a link that points to the file. Attack ScenarioĪssigned CVE-2016-2208, this vulnerability is easy to trigger. To quote Tavis on this one, this is as bad as it gets. That means the code that the attacker is executing gives them root privileges on Linux, Mac and other Unix variants running affected Symantec products, and not just administrative access, but kernel-level code execution on Windows. One would assume that a product running on a system would need elevated privileges in order to handle antivirus tasks. By altering some basic size parameters in the packed code’s headers, size discrepancies cause memory allocation errors in this Antivirus Decomposer engine and bingo! Code execution of the attacker’s choice by supplying a chunk of code that will trigger this flaw. This technique of using packers is in itself not malicious, as many code developers are familiar with and use the technique, but what this means is an antivirus product has to automatically unpack the packed code so that it can be examined for maliciousness. The Main VulnerabilityĪs a member of the Project Zero team at Google, Tavis released an advisory that details memory corruption when using crafted malicious files to trigger a flaw in the Symantec Antivirus Decomposer engine, an engine used in pretty much the entire Symantec and Norton security product line including their flagship product Symantec Endpoint Protection.Ī common technique for malicious code authors is to use “packers” to compress the size of their malicious code. So it is no surprise that on Ja vulnerability in Symantec’s Antivirus Decomposer engine, used in Symantec Endpoint Protection and other Symantec and Norton security products, was acknowledged by Symantec Corporation in a security advisory issued by the company, and we all loved and hated Tavis all over again. Norton AntiVirus is an anti-virus or anti-malware software product, developed and distributed by NortonLifeLock since 1991 as part of its Norton family of. This hate is compounded when the bug is easy to exploit and you have that feeling of “if I had only looked there first….” The life of a security researcher is like this. We typically love his work, but we hate it when he finds a particularly juicy bug. Norton AntiVirus will display the results of the scan.I think most security researchers have this love/hate relationship with Tavis Ormandy.
